There’s just one catch: every atom in your body would be fully disassembled to the quantum level, effectively leaving your original body totally destroyed.

  • I believe current understanding is that quantum shenanigans mean you can’t truly make a perfect quantum duplicate of something without destroying the original at the same time, so what you’re describing (destroying the original after making the copy) would only be possible for imperfect duplication - e.g. manufacturing a clone and syncing its memory with the original.
